Two passengers of a US-Bangla Airlines flight suffered "minor injuries" from a bullet "accidentally" fired from the pistol of a lawmaker's son in Barisal Airport on Monday.

Police filed a general diary over the "accident", but made no mention of any injuries.

The incident happened a few minutes before Awami League lawmaker Abul Hasanat's son Moin Abdullah was about to board the Barisal-Dhaka flight at 3:30pm.

In front of the airlines' boarding counter, Moin was unloading his pistol when a bullet was fired accidentally, bounced off the floor, and hit the two passengers, said Kamrul Islam, public relations  officer of US-Bangla Airlines. He said a firearm had to be unloaded and packed in a checked bag for transportation. The two "unidentified" passengers travelled on the same flight that Moin, his brother Ashik Abullah, and their mother Sahanar Begum took. Hanif Gazi, manager of Barisal Airport, said he was not present at that time, but heard two passengers suffered minor injuries from the accidental firing. An investigation committee will be formed today, he added. Nurul Islam, officer-in-charge of Barisal Airport Police Station, confirmed a GD was filed.
